A number of subdivision branches can be associated with every geography level.

For example,
there are four subdivision branches associated with the "US.ZIP5" geography level—"USbyZIP5", "StatesByZIP5", "DMAsByZIP5", and "CBSAsByZIP5". The "USbyZIP5" branch for this level represents a subdivision of USA in ZIPs having the depth of 3—the whole USA has the depth 0, US States have the depth 1, US Counties have the depth 2, and ZIP5 codes have the depth 3 in this subdivision branch.
